About ICD-9-CM V29.3
V29.3 is an ICD-9-CM diagnosis code for observation for suspected genetic or metabolic condition. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as Z05.41 (Observation and evaluation of newborn for suspected genetic condition ruled out) and Z05.42 (Observation and evaluation of newborn for suspected metabolic condition ruled out). All of these are approximate matches, so review the record to pick the right one.
